LAMP-=CONTROLLING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 312,944, dated February2%, 1885.

. isms,of which the following is a full,clear, conlocality at anydistance from the lamp.

cise, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification, sufficient to enableothers skilled in the art to make and use the same.

The object of my invention is to provide means whereby a lamp, whetherelectric (arc or incandescent) or any other class .of lamp, may becontrolled as regards the direction which the rays of light therefromshall be caused to take, this control being from any As, for example,the merit and usefulness of my invention is apparent on shipboard,where, by it, lamps at the mast-head or any other portion of the vesselmay be controlled, as to the direction in which the light shall bethrown, from the pilot-house, cabin, or any other convenientpoint. Inthe same manner elevated electric or other lamps mounted upon buildings,masts, or eininences may be controlled from the ground or at anylocation at any distance from the lamp.

My invention consists in certain features of construction hereinafterdescribed, and specifically set forth in the claims.

Referring to the drawings, Figurel is a side elevation of a lamp-frame,with lamp and means for controlling same in accordance with myinvention.Fig. 2 is amodification. Fig. 3 is a top view of the side-movingmechanism. Fig. 4 is a top view of the frame for the lamp. Fig. 5 is aplan of the upper supportingjournal.

A at its top and bottom, in line with each other, and adapted to supportthe lamp vertically and admit of its rotation. A spring Applicationfiled May 2 1, 1884. (No model.)

cushion, B, is inserted between the frame work, and a bracket, G, havinga brass box, B, in which is a bearing for the pivot A. The upper pivotpasses through a bearing formed in a bracket, 0, and both brackets aresecured in any convenient manner to a mast of a vessel, or any otherobject which serves the purpose of supporting a lamp in any desiredposition, themeans of supporting and the manner of connecting thebrackets thereto being mere matters of mechanical skill, and thereforerequiring no further description. WVhen an electric lamp, either of theare or incandescent pattern, is in use, to one of the brackets aconductor, D, is connected with the positive pole of a battery or otherelectrical generator, while to the brass bearing of the lower bracket isconnected the conductor D from the opposite or negative pole, and thenceby suitable connections to the lamp. In the bracket 0 the bearing 0 forthe-upper pivot consists of a central collar, 0, adapted to fit thepivot, and a series of springs, 0, arranged in the same horizontal planeand about said collar, and bearing against the periphery thereof andagainst the inner walls of the chamber 0 formed in the bearing portionof the bracket 0. By the spring-cushion B at the lower portion of thelamp-frame a vertically-yielding support is provided, and by thepeculiar bearing of the upper pivot a laterally-yielding support isprovided, so that the movements of the vessel or other vehicle uponwhich the lamp is supported are partially compensated for or overcome,and the lamp is held practically motionless. Now, in order to direct therays from the lamp in different directions at will, it remains toprovide means for rotating the frame horizontally and inclining the lampvertically, so that the directionof its rays may be determined to exposeto view objects in depressed or elevated positions or to the right orleft, as may be desired.

To produce the rotation of the lamp-frame and any lamp suitably placedtherein, I secure to the upper pivot, either below the bracket 0 orabove the same, as desired, a pulley, E, and I conduct about the same acord, E, or its equivalent, to the structure,

mast, or other means of support, and thence about one or more pulleys, Elocated, for the instance, in the pilot-house of a vessel, thelamp beingsupported by a mast, so that by pulling said cordin one direction and inanother the lamp-frame, and the lamp contained therein, will be rotatedhorizontally to any desired extent. It now remains to provide forinclining the lamp bodily or oscillating it in a vertical plane, inorder to elevate or depress the rays of light therefrom. I have showntwo constructions for attaining this object.

In Fig. 1 an inclined movable bottom, F, is provided in a frame uponwhich a lamp is supported, and said bottom is hinged, as at F, to thetrue bottom of the frame. A cord, F is secured to the free edge of saidinclined bottom, and passes through the pivot A over a pulley orpulleys, F to any suitable reel, as F, located adjacent to the pulley orpulleys E so that bot-h cords for controlling the movements of the lampand frame shall be within easy access of the operator. The highest pointof the lamp and its rays being when the platform F is at rest upon thetrue platform, it follows that in order to direct the lamps rays to anypoint of declination, it is only necessary to raise the platform bymeans of cord F.

In order to prevent the lamp from going too far forward, it may besecured by a short chain or other flexible connection to the bottom F.

In Fig. 2 I have provided for inclination in vertical planes by simplysupporting the lamp upon the trunnions G within the frame A. The cord Fin this modified construction will be connected to the lamp-body at thebottom. The gravity of the lamp may be depended upon to retain it in avertical position, or counteracting-sprin gs may be employed, whichshall normally hold the lamp in such a position as to direct its rays inan upwardly-inclined direction, and it may be held so that the raysshall project therefrom in a horizontal line by means of the cordoperating in opposition to the spring, and so hold the lamp, or to holdit in such a position as to direct its raysinadownwardly-inclined,direction. The flexibility of the connectionthatis,the cord admits of the horizontal rotation of the lampframe and itscontained lamp to any practically-required distance.

Various modifications will suggest themselves to persons skilled in theconstruction of lamps and lamp-supports, and I do not limit my inventionto the exact details herein shown and described; but I may alter thesame to any extent and in any manner within the skill of persons of theclass mentioned, and although I may specify the element or elements ofconstruction by which my lamp-support is adapted to be used inconnection with electric lamps, I do not confine myself in that respect,as it is evident that any light-giving devices at present known or usedmay be substituted for the electric lamp and be controlled as to thedirection in which its rays shall fall or proceed by the same meanswhich would be employed to so control the rays of light from anelectriclamp.

Having thus described my invention, what I claim is- 1. The combinationof a lamp frame or support, a bracket, a trunnion mounted in the bracketand connected with the lamp-frame, and a pivoted lamp-support anddevices, substantially as shown and described, forinclining the lamp androtating the lamp-frame or support, substantially as specified.

i 2. The combination of a bracket, a lampframe having a pivot ortrunnion mounted in bearings in the bracket, a lamp-holder pivotallysupported in the frame, a pulley secured to the pivot or trunnion, andmeans for rotating the pulley, substantially as specified.

3. The combination of a bracket, a lampframe pivotally mounted therein,a lamp pivotally supported in the frame, means for inclining the lamp,and means for rotating the lam p-frame, substantially as specified.

4. The combination of a lamp-bracket, a lamp-frame supported therein bya vertical pivot or shaft, a lamp vertically supported in.

said frame for inclination, and a cord arranged for inclining the lampor its pivotal support, and a cord for rotating the frame, substantiallyas specified.

5. The combination, with a lamp-frame having vertical t-runnions orpivots, of horizontally-pivoted lamp-supporting devices, a pulleymounted upon one of the vertical trunnions, and cords arranged tooperate said pulley and to incline said lamp-supporting devices,substantially as specified.

6. In combination with a lamp-supporting frame having a vertical pivot,a bracket provided with a bearing for said pivot,yieldingly supported inlateral directions to said pivot, substantially as specified.
